Scientists from the University of Rochester revealed their latest (and coolest) discovery: an invisible cloak! These ‘wizards’ found a way to hide large objects from sight with a variety of inexpensive lenses and everyday materials, based on a technique that came from the very same pages of J.K. Rowling’s Harry Potter books. According to the scientists, through this technique they are able to hide objects from view leaving their surroundings looking exactly the same. John Howell, a professor of physics at the University of Rochester said, “Many people have approached different aspects of the idea of ‘cloaking’ for many years, but instead they use high-tech or exotic materials.”
Howell and graduate student Joseph Choi, called the device the “Rochester Cloak” which isn’t in fact a cloak. It looks more like a piece of equipment an optometrist would use. Choi explained that the device has four standard lenses that allow an object to appear invisible as the viewer moves several degrees away from the "optimal viewing position." Choi then added proudly that, “The "Rochester Cloak" is the first of its kind, as it's capable of three-dimensional, continuously multidirectional cloaking."
Both scientists think the discovery could have multiple uses other like, “helping bus drivers see what’s directly behind them if they have a huge trailer or another object blocking their view; or even surgeries, military purposes, interior design or art.” Howell said he was inspired to construct the device while working on a holiday project with his children.
